Test: Numbers - 5 - CTET & State TET MCQ

The place value of a number is the value of the digit in the given number.
The place value of the underlined digit in the number 7,65,730 is 7,00,000 as it is in the lakhs place.

In a 5-digit number, the first three places from the right are the ones, tens, and hundreds places. These make up the ones period. The thousands period consists of the thousands and ten thousands places, which are the fourth and fifth places from the right

There are three ten thousands, five thousands, six hundreds, three tens and five ones in the number 35,635. Hence, we read 35,635 as thirty-five thousand six hundred and thirty-five.

4 x Lakh + 5 x Ten-Thousand + 0 x Thousand + 0 x Hundred + 0 × Ten + 0 × One

= 4 x 100000 + 5 x 10000 + 0 x 1000 + 0 x 100 + 0 x 10 + 0 x 1

= 400000 + 50000 + 0 + 0 + 0 + 0

= 400000 + 50000

= 450000

= Four Lakh fifty thousands

In the standard form, we write 40,000 + 6,000 + 700 + 80 + 1 as 46,781.

The correct answer is (d).
In a five-digit number, the Thousands period represents the highest numerical value. It is followed by the Hundreds period, Tens period, and Ones period, in descending order of value.

a) Divided into two periods: Ones and Thousands

Explanation:

A five-digit number (e.g., 12,345) is structured in the following way:

1. Two Main Periods:

   • Thousands period (first two digits from the left: Ten Thousands and Thousands).

   • Ones period (last three digits: Hundreds, Tens, and Ones).

2. Why Not Other Options?

   • b) Three periods (Hundreds, Tens, Ones) → Missing the Thousands period.

   • c) Four periods → Incorrect; five-digit numbers only have two periods (Thousands and Ones).

   • d) Hundreds and Thousands → Incorrect; the correct division is Ones and Thousands.

Key Takeaway:

• Five-digit numbers are split into two periods:

  • Thousands (Ten Thousands + Thousands place).

  • Ones (Hundreds, Tens, Ones place).

Example:

• 52,819 →

  • Thousands period: 5 (Ten Thousands) + 2 (Thousands).

  • Ones period: 8 (Hundreds) + 1 (Tens) + 9 (Ones).

Final Answer:
a) Divided into two periods: Ones and Thousands

1,00,000 is equal to 100 thousands.
1,00,000 is read as one lakh.
Hence, 1,00,000 can be expressed as 100 thousands.

There are 2 beads in the lakhs place, 4 beads in the ten thousands place, 6 beads in the thousands place, 0 beads in the hundreds place, eight beads in the tens place and one bead in the ones place.
Hence, the number on the abacus is 2,46,081.

99,999 is the greatest 5-digit number.
When 1 is added to 99,999, we get the 6-digit number 1,00,000.

The smallest 6-digit number is 1,00,000.

99, 999 is the greatest 5-digit number.

One lakh can be written in figure like 1,00,000.

4, 23, 456 can be written in words like Four lakh twenty-three thousand four hundred fifty six 

Last three places of a number is the ones period consist of hundred, tens and ones.

6, 46, 555 = 600000 + 40000 + 6000 + 500 + 50 + 5

Ten lakhs come under the third period of the Indian numbering system, that is, lakhs period.

Instead of putting comma, we can leave space to separate the periods.

All periods are separated by a comma while writing the number in its numeral form.

300000 + 20000 + 4000 + 200 + 20 + 2 = 3,24,222
